我想在 ASP.NET Core 中实现基于 JWT 的安全性.我现在要做的就是读取按钮 @Html.ActionLink(Test",Oper",Home") 中的令牌，授权标头并验证它们违背我的标准.我不知道错过了什么，但它总是返回 HTTP 401 代码.
I want to implement JWT-based security in ASP.NET Core. All I want it to do, for now, is to read tokens in the button @Html.ActionLink("Test","Oper","Home") , authorize header and validate them against my criteria. I don't know what missed but it is always returning HTTP 401 code.
文件HomeController.cs
private string GenerateJSONWebToken(UserPaul userinfo)
{
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
var claims = new[]
{
new Claim(JwtRegisteredClaimNames.Sub,userinfo.Username),
new Claim(JwtRegisteredClaimNames.Email,userinfo.Email),
new Claim(JwtRegisteredClaimNames.Jti,Guid.NewGuid().ToString()),
};
var token = new JwtSecurityToken(
issuer: _config["Jwt:Issuer"],
audience: _config["Jwt:Issuer"],
claims,
expires: DateTime.Now.AddMinutes(10),
signingCredentials: credentials
);
var encodetoken = new JwtSecurityTokenHandler().WriteToken(token);
var cookieOptions = new CookieOptions();
cookieOptions.HttpOnly = true;
cookieOptions.Expires = DateTime.Now.AddMinutes(1);
//cookieOptions.Domain = Request.Host.Value;
cookieOptions.Path = "/";
Response.Cookies.Append("jwt", encodetoken, cookieOptions);
return encodetoken;
}
[HttpPost]
public IActionResult Login()
{
string AccountNumber="TestUser";
JWTtokenMVC.Models.TestContext userQuery = new JWTtokenMVC.Models.TestContext();
var query = userQuery.Testxxxx.Where(N => N.UserId ==AccountNumber).FirstOrDefault();
IActionResult response = Unauthorized();
if (query != null)
{
var tokenStr = GenerateJSONWebToken(query);
response = Ok(new { token = tokenStr });
}
return response;
}
[Authorize]
[HttpGet("Home/Oper")]
public IActionResult Oper()
{
var authenticationCookieName = "jwt";
var cookie = HttpContext.Request.Cookies[authenticationCookieName];
List<Test_SHOW> sHOWs = new List<Test_SHOW>();
JWTtokenMVC.Models.Test.TestContext userQuery= new JWTtokenMVC.Models.Test.TestContext();
var query = userQuery.Test.Select(T => new Test_SHOW
{number= T.number,name= T.name,mail= T.mail}).OrderBy(o => o.Iid);
sHOWs.AddRange(query);
return View("Views/Home/Oper.cshtml", sHOWs);
}

Startup.cs 添加 UseAuthentication
Startup.cs Add UseAuthentication
所以我假设您正在尝试使用 Angular 项目的 asp.net core.我认为您错过了将客户端 URL 添加到您的 .net core 项目.AddCors对 IServiceCollection 的扩展调用只是注册了所有需要的服务，但它没有将 Cors 中间件添加到 HTTP 请求管道中.所以添加此代码 app.UseCors(x => x.AllowAnyHeader().AllowAnyMethod().WithOrigins("https://localhost:4200")); 在您的 Configure 方法中.我认为它可以解决您的问题.
So I assume you are trying asp.net core with an angular project.I think you are missed adding your client-side URL to your .net core project. AddCorson extension call for IServiceCollection just registers all required services, but it does not add Cors middleware to the HTTP request pipeline.So add this code app.UseCors(x => x.AllowAnyHeader().AllowAnyMethod().WithOrigins("https://localhost:4200")); in your Configure method.i think it's resolve your issue.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
//clarify code
}
else{
//clarify code
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(x =>
x.AllowAnyHeader().AllowAnyMethod().WithOrigins("https://localhost:4200")); //your client side URL.you are missing this unfortunately
app.UseAuthentication();
app.UseAuthorization();
//clarify code
}
更新
安装Microsoft.AspNetCore.Cors
只需删除 AllowCredentials() 即可解决您的问题.
Just remove AllowCredentials() and it's will fix your issue.
